Machining Processes for Precision Molds

INTRODUCTION The continuing drive towards miniaturisation in a number of industries including semiconductor, optoelectronic and medical is stimulated by requirements which include enhanced functionality, performance and reliability, increased energy efficiency, a cleaner environment, improved healthcare, together with reduced costs etc. [1, 2]. Also, new products for fastgrowing industries like...

Microfactory -novel Manufacturing Systems for Precision Machining-

1. FIRST PROPOSAL; MICROFACTORY “Microfactory” was a concept of a future manufacturing system, which was proposed in the Japanese national R&D project named “Micro Machine Project [1].” The original concept of the microfactory was a super-miniature manufacturing system that consists of miniature machine tools and manipulators. In 1999, AIST developed the first prototype of a microfactory. (Figu...

Ultra-precision Machining Systems; an Enabling Technology for Perfect Surfaces

The technology of ultra-precision machining, spanning almost three decades, has only in recent years experienced major advances in machine design and, subsequently, performance and productivity. In the 1970’s, ultra-precision machining techniques were successfully adopted for the manufacture of computer memory discs used in hard drives, and also photoreceptor components used in many photocopier...

Development of Ultra Precision Machining with High Positioning Resolution

INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...
